With today's 10.14.4 DP2, Apple released MP5,1 BootROM 141.0.0.0.0:

  • Build date is 20181219
  • CRC32 is 58ee7535.

Code:
$IBIOSI$ MP51.88Z.F000.B00.1812191621
‰Apple ROM Version
  Model:        MP51
  EFI Version:  141.0.0.0.0
  Date:         Wed Dec 19 16:15:33 2018
  Build Type:   Release

I'm still checking it, gonna reconstruct and flash it. I'll post what I'll find.

One thing of note, kudos to Apple doing more BootROMs, I don't remember another Mac getting firmware updates after being put into vintage list.

141.0.0.0.0 NVMe module is the same as 140.0.0.0.0, so changes are elsewhere:

141.0.0.0.0 - NVMe Module.png

[doublepost=1549325501][/doublepost]Same microcodes as MP51.0089.B00:

140.0.0.0.0 - microcodes.png
141.0.0.0.0 - microcodes.png

[doublepost=1549326171][/doublepost]There are a lot of changes between 140.0.0.0.0 and 141.0.0.0.0, HexFiend found 26021:

[doublepost=1549326572][/doublepost]Exactly the same empty NVRAM volume as 140.0.0.0.0:

Probably a long shot, but any such luck for an SMC update for the 2009 Mac Pro.

@tsialex : Where in can download 10.14.4 DP 2 full installer to install Bootrom 141.0.0.0.0? The update via systemupdate does not install Bootrom. Can I update Bootrom to 141.0.0.0.0 with http://swcdn.apple.com/content/down...36lz5n9k4v43nisc536ce99df3/FirmwareUpdate.pkg too?

Is there a new Hardware listing for APPLE PAY on Mac Pro as part of this firmware update, or was that just part of the latest beta? Hard to tell from screenshots posted above.

Don't get me wrong, but if you don't know where the firmware is hidden by Apple, why on earth you want to install a beta firmware just released?

People, this is a beta firmware. Let people with skills to reprogram the SPI flash externally/replace the backplane do the tests, then you can think about.

I'm not going to post where the firmware is this early on. If you really want to know, read the thread, there are a lot of breadcrumbs.

Any change with bootscreen? @tsialex
Dream on, Part III. ;)

Don't make sense extensively modify the firmware of all Macs to implement support of a hardware feature that is not present into most, I'm thinking this is not the motive.

I just started to look, but some modules that changed have a INTEL RSVD string…

Unrelated to 141.0.0.0.0, just found another mystery EFI version into a BootBlock:

Code:
APLEFI1.88Z.0005.I00.1006041028

This one is from a very early 2010 MP5,1 and was released more than 4 months before MP51.007F.B03:

Code:
APLEFI1.88Z.0005.I00.1010071430

I started a spreadsheet with all EFI versions that I find into dumps. Maybe we will find something interesting.

Just did a rapid check into 18D109, same 140.0.0.0.0 BootROM.

Tsialex - are you now convinced that the 141 BootROM is focused on security improvements, or are you still in the process of reviewing it for changes?

Everything I saw until now seems to point that Apple released 141.0.0.0.0 as a security update, but I can be wrong.

I'm very busy this month and I'm looking this when I have time and I'll have to check a lot of things yet.

just for clarification:
140 has been out
141 is in beta

140 added a lot of features, including NVMe boot
